Come home, Cesc

And reports suggested Fabregas - who has also been linked with a return to Arsenal - could head to the Etihad Stadium in part-exchange for the striker.

But City insist that Aguero will not be going anywhere and they have no intention of bidding for Fabregas, regardless of whether the deal involves the Argentine.

Fabregas is set to leave Barcelona this summer after three seasons at his hometown club, with Barca having reportedly set a £30 million asking price.

He was a target for Manchester United last year and has scored 42 goals in 151 games since leaving Arsenal for £35m in 2011.

Fabregas established a reputation as one of the Premier League's best attacking midfielders during his time at Arsenal, for whom he scored 57 goals in 303 games.

However, the former Barcelona player Yaya Toure has been prolific in the same role for City, scoring 24 times this season, and they remain determined to keep the Ivorian despite a bizarre stand-off over his 31st birthday with the player's agent.

Aguero, who celebrated his 26th birthday on June 2, has been consistently linked with a return to Spain since he joined from Atletico Madrid in 2011.

But, like Toure, he signed a four-year contract in 2013, committing him to City to 2017 and manager Manuel Pellegrini has always maintained Aguero is happy and that he does not want to sell the striker.

Aguero scored 28 goals last season and has struck 75 times in his three years in England to make him a key player for City. Even Del Castillo admitted he thought City would make it "impossible" for his son to leave.
